And we all have Ruben Wiki, a trainer for the New Zealand Warriors and a former rugby player, to thank for the helpful demonstration, captured here by the Otago Daily Times of Dunedin, NZ. A naked man had dashed across the pitch during halftime of Saturday's National Rugby League trial game between the Warriors and the Brisbane Broncos. Wiki took him down and was able to hold on until security arrived, though the trespasser did manage to squirt free before security took him down again. But all credit to Wiki for his willingness to be first to face down the intruder.
